Do the following steps as root:
edit your /etc/apt/sources.list: add the line:

deb http://ftp.de.debian.org/debian wheezy main

then run

apt-get update

If there is an error („too many package descriptions“): comment out some other entries in /etc/apt/sources.list. Go on with

apt-get install debian-keyring/testing

apt will remove debian-maintainers, but I don’t think this package is neccesary.
change your /etc/apt/sources.list back to its original contents.

apt-get update

Change back to your normal user.

Now you can verify the images by first downloading the iso-file and the corresponding SHA512SUMS and SHA512SUMS.sign files from the same directory (for 64bit PC: http://cdimage.debian.org/debian-cd/6.0.0/amd64/iso-cd/).

You can ignore the „FAILED open or read“ lines – sha512sum just looks for all cd images listed in the file. The „OK“ line must be there.

Now you have successfully verified the ISO – have fun installing!
